Response of the eukaryotic plankton community to the cyanobacterial biomass cycle over 6 years in two subtropical reservoirs

The ISME Journal, Journal Year: 2019, Volume and Issue: 13(9), P. 2196 - 2208

Published: May 3, 2019

Abstract Although it is widely recognized that cyanobacterial blooms have substantial influence on the plankton community in general, their correlations with whole of eukaryotic at longer time scales remain largely unknown. Here, we investigated temporal dynamics communities two subtropical reservoirs over a 6-year period (2010–2015) following one biomass cycle—the bloom (middle 2010), cyanobacteria decrease (late 2010–early 2011), non-bloom (2011–2014), increase, and second 2014–2015). The succession strongly correlated this cycle was divided into four periods, each had distinct characteristics environments both reservoirs. Integrated co-occurrence networks based study revealed remarkably high network centralities, OTUs stronger exhibited higher centralities. integrated were also modularly responded to different therefore cycle. Moreover, sub-networks periods indicated patterns not constant but varied associating biomass. Based these long-term observations, our results reveal created niches between persistent bloom, non-bloom, increase cyanobacteria, associated patterns. Our important implications for understanding how complex aquatic respond under changing environments.

Ecological networks of dissolved organic matter and microorganisms under global change

Nature Communications, Journal Year: 2022, Volume and Issue: 13(1)

Published: June 23, 2022

Abstract Microbes regulate the composition and turnover of organic matter. Here we developed a framework called Energy-Diversity-Trait integrative Analysis to quantify how dissolved matter microbes interact along global change drivers temperature nutrient enrichment. Negative positive interactions suggest decomposition production processes matter, respectively. We applied this manipulative field experiments on mountainsides in subarctic subtropical climates. In both climates, negative bipartite networks were more specialized than interactions, showing fewer between chemical molecules bacterial taxa. Nutrient enrichment promoted specialization but decreased indicating that was vulnerable by greater range bacteria, particularly at warmer temperatures climate. These two influenced most strongly via molecular traits, while traits diversity similarly affected interactions.

Recent advances in polysaccharide‐based hydrogels for synthesis and applications

Aggregate, Journal Year: 2021, Volume and Issue: 2(2)

Published: Jan. 19, 2021

Abstract Hydrogels are three‐dimensional (3D) crosslinked hydrophilic polymer networks that have garnered tremendous interests in many fields, including water treatment, energy storage, and regenerative medicine. However, conventional synthetic hydrogels poor biocompatibility. In this context, polysaccharides, a class of renewable natural materials with biocompatible biodegradable properties, been utilized as building blocks to yield polysaccharide‐based through physical and/or chemical crosslinking polysaccharides via variety monomers or ions. These polysaccharide‐derived exhibit peculiar physicochemical properties excellent mechanical due their unique structures abundant functional groups. This review focuses on recent advances synthesis applications by capitalizing set (i.e., cellulose, alginate, chitosan, cyclodextrins [CDs]). First, we introduce the design principles for crafting hydrogels. Second, interconnected various strategies (e.g., crosslinking, double networking) summarized. particular, introduction noncovalent dynamic covalent interactions imparts myriad intriguing performances stimuli–response self‐recovery). Third, diverse self‐healing, sensory, supercapacitor, battery, drug delivery, wound healing, tissues engineering, bioimaging fields discussed. Finally, perspectives promote future enable new functions outlined.

Biodiversity science in China has seen rapid growth over recent decades, ranging from baseline biodiversity studies to understanding the processes behind evolution across dynamic regions such as Qinghai-Tibetan Plateau. We review research, including species catalogues; monitoring; origins, distributions, maintenance and threats biodiversity; biodiversity-related ecosystem function services; ecosystems' responses global change. Next, we identify priority topics offer suggestions priorities for future research China. These include (i) ecology biogeography of Plateau surrounding mountains, that subtropical tropical forests China; (ii) marine inland aquatic (iii) effective conservation management maintain synergies between socio-economic development fulfil China's vision becoming an ecological civilization. In addition, propose three strategies: translate advanced into practice conservation; strengthen capacity building application technologies, high-throughput sequencing, genomics remote sensing; expand international collaborations. Based on progress is well positioned become a leader near future.

Understanding the spatial distributions and ecological diversity of soil archaeal communities in agricultural ecosystems is crucial for improvements crop productivity. Here, we conducted a comprehensive, continental-scale survey adjacent pairs maize (dryland) rice (wetland) fields eastern China.We revealed consequential roles environmental filtering driving community assembly both fields. Rice fields, abundant with Euryarchaeota, had higher steeper distance-decay slopes than dominated by Thaumarchaeota. Dominant archaea showed distinct continental atlases niche differentiation between dryland wetland habitats, where they were associated pH mean annual temperature, respectively. After identifying their preferences, grouped dominant taxa into different clusters determined unique co-occurrence patterns within each cluster. Using this empirical dataset, built atlas to provide reliable estimates ecosystems.Environmental plays role wetland, contrasting strategies archaeal-driven nutrient cycling these two ecosystems. These findings improve our ability predict how respond changes manage provisioning ecosystem services.

The impact of atmospheric vapor pressure deficit (VPD) on plant photosynthesis has long been acknowledged, but large interactions with air temperature (T) and soil moisture (SM) still hinder a complete understanding the influence VPD vegetation production across various climate zones. Here, we found diverging response productivity to in Northern Hemisphere by excluding interactive effects T SM. between T/SM not only offset potential positive warming also amplifies negative effect drying. Notably, for high-latitude ecosystems, there occurs pronounced shift productivity's during growing season when surpasses threshold 3.5 4.0 hectopascals. These results yield previously unknown insights into role terrestrial ecosystems enhance our comprehension carbon cycle's global warming.
